After reawakening on May 20, 1883, Krakatau generated mild detonations from Perboewatan throughout May and June. By mid-June the summit crater of Perboewatan had been largely destroyed and the cite of eruption widened to include several new vents near Danan. By mid-July, banks of pumice were common features found floating in the Sunda Straits. However, some of the earliest tephra was basaltic, indicating that recharge of basalt magmas into the magma chamber beneath Krakatau may well have played a role in the intiation of these early eruptions.
On December 29, 1927, a group of Javanese fisherman who were startled by steam and debris bleching from the sea above the collapsed caldera, thus marking the reawakening of Krakatau after 44 years of calm. The activity continued, and on January 26, 1928 the rim of a basaltic scoria cone first appeared above sealevel. A year later, it had grown into a small island which was quickly dubbed Anak ("Child of") Krakatau.
Anak Krakatau has erupted in most years since. Typically, these are rather mild strombolian to vulcanian eruptions of basaltic andesite lava flows and associated tephra deposits. Although they present little danger to surrounding islands, the eruptions from Anak Krakatau provide a constant reminder of the horror of 1883 - Lest we forget.
